[Résolu] enthalpie libre

Messagepar Narinette » 22 Mar 2023, 22:08

Salut !

J'ai une petite question sur le DM d'annales de chimie thérapeutique. La correction de 2014 indique pour le qcm 2 : "Variation de l’enthalpie libre négative" FAUX
Alors que pour le même item en 2021 paces qcm 2, il est compté VRAI
Du coup je ne comprends pas trop..

Merci !
Narinette

Je pense que c'est faux ma ptite Marine, mais j'attends la confirmation de Mélanie

C'est bien faux !

C'est bien faux, confirmé par la biochimie, les enzymes ne peuvent pas rendre une réaction thermodynamiquement défavorable -> favorable
